Faraday isolators

Faraday isolators are essentially optical one-way devices, largely blocking radiation in one direction. They can be used, for example, for protecting lasers and laser amplifiers against optical feedback. There are bulk devices as well as fiber-coupled isolators, some of which are polarization-sensitive.

Interactive Purchase Decision Tool

Purchasing high-value photonics products is a substantial responsibility. Using a structured decision-making process and high quality supplier data helps a lot:

Go through the process:

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you purchase.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

To help you, we have already listed some aspects we recommend you consider when buying Faraday isolators. Of course, there may be other aspects that are relevant to your specific case.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

Otherwise, you will need to talk to your technical colleagues.

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable suppliers

We suggest three steps:

  • Below, you can find our list of suppliers for Faraday isolators. Use the checkboxes to mark possibly suitable suppliers.
  • The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
  • Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

4. Document the decision process

It is essential to document your purchasing process, not only its result (chosen supplier):

  • You will find it easier next time.
  • If something goes wrong, you can defend your decision by showing that you properly considered all important aspects. Or you see what needs to be done better next time.

Our interactive tool makes it easy: Fill out the form, and in the end print it to a PDF. Note that the document will show all sections (including those not currently shown on the screen), while omitting some irrelevant details such as the page navigation.
